tannins-MACHINE.

To all whom, it may concern: v

Be it known that I, BERNARD I-I Aenm,"a citizen of theUnited States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and usefullmprovements in Labeling-Machines, of which the'following is aspecification. I

My invention pertains to label-aflixing appliances and concerns more particularly, but not exclusively machines ofthis type or character for applying labels to batches of dough before baking, such, for example, as. the pieces of dough for loaves of bread, no paste, glue, or-the like being employed, the

natural adhesive properties of the dough that particular body of dough, whereby, if

the travel of the batches is temporarily interrupted, such a properly-timed cessation of the feeding and cutting off of labels will occur, that none are wastedand the apparatus does not become'clogged byreason of improper and unnecessaryv operation of the device.

The prime and leadingobject of the invention and one of its salient featuresis the provision of a label-affixing apparatus of this character which, because of its simplicity in structure, is economicalto manu facture, which is unlikely to become deranged or injured in service, which feeds,

cuts,and applies the labelswithj certainty and efiectiveness, which wastes no labels,v and which requires but little attention toassure continuous, efiicient, and reliable op eration, These and various other objects and aims are accomplished or attained in the employment of a device incorporating/this invention, which, it should be understood, isv susceptible of a varietyof embodiments and.

is not, therefore, limited and restricted in Specification of Letters Patent. V Patented Feb, 10, 1920. Application filedjNovemb er 14', 1918. Serial No. 262,424.

its successful commercial application to the special features. of structure and function of any one particular concrete eX'ample'of the invention inphysical form.

In order that those skilled in this art may have a full and complete-understanding of I the invention 1 and its various advantages" bothfroni a structural andfunctional stand; point l have illustrated in the accompanyingdrawings, forming a part of this specification and throughout the various views of which like reference characters refer to the j same parts, a preferred and desirable embodiment of the invention.

" Fig. 9 shows 1n a general way the association of this improved device with a dough-molding machine. r j I Referrin first to Fig. 9 it will be seen that the la eling apparatus is so connected to or combined with an ordinary moldinginachine comprising a rotary drum 20 and 7 its associated spaced band 21, that the trip or trigger 22 of the appliance is disposedin the annular space betweenthe two. parts of the inolder, whereby'it willbe subject to actuation by the individual batchesof doughas they pass along through the inolder, such trip" member eifecting the'feed and sever ance from a continuous strip23 of .labelsof the foremost label 24 so; that it will be jin troduced through an aperture'25 in theband of the molderinto the path oftravel of the body-"of dough to which it automatically, lbecomes adhered by reason of the adhesive} 'ness of; the dough itself, If the 'feed o f the dough ceases, the appliance will not be tripped and nolabels will be fedor cutoff. Turning now to the label advancing and severing part'of the apparatus, it willbe I seen that it includes a suitably-supported base-plate 26 having alined, transverselydisposed, bearings 27, 27- for an intermittently-actuated shaft 28 having a collar 29 pinned or otherwise fixedly secured thereto,

locked against turning, Loose and free to V. rotate on this shaft is a grooved'pulley 31 constantly rotated in a counter-clockwise direction as viewed in Fig. 2by' 'a belt'driven from any suitable source of power, conveniently from a pulley on the shaft (not shown) of .the molder drum. The hub of such'pulley has one face equipped with friction material 32 adapted to bear against the adjacent face of collar 29 and'to rotate the latter and the shaft when permitted to do so. These partsare pressed together longitudinally of theshaft into friction driving relation by a coil expansion spring 33 encircling the shaft and bearing atone end against the hub of the pulley and at its other end against an adjustable abutment .4 held rigidwith the shaft.

To prevent the shaft from turning, a lock lever 35 is fulcrumed at 36 on a depending arm 37 of the base-plate and by means of a torsional spring 38 coiled around its fulcr'uin screw and looped around the lever and secured to the base-plate, the former is maintained elevated'so that its end is in the V path'of circular travel'of lug 30, its engagement with which prevents the shaft from rotating with the constantly revolving puli e i p lnforderto trip or releasethis lock-lever, themachine is provided with a more or less upright shaft 40 square in'cross-section revoluble in a swiveled'bearing 41 on adownwardly-projecting part of-the appliance, the

' 'shaft'having a cam-arm 42"adapted to ooact with a-cam portion 43 of lever 35. Thus when cam 42 is swung inwardly it rocks lever 35, temporarily releasing lug 30, enabling the shaft and collar-to make one complete revolution with the pulley by reason ofthe friction clutch construction. "By the time lug 30 has completed such single revolution, cam '42 will have been'rockedout of theway allowing lever 35 tobe in normal position toj'engage the lug and inhibit further rotation thereof until again tripped.

will be described hereinafter. V V

I At its other end shaft 28; carries a disk 4'4with a'wrist-pin 45 on which is'a con- The-mea'ns fo'r'oscillati'ngthe trip shaft 40 'ne'cting rod '46pivoted at 47 to a depending arm'48 on a horizontal sliding carriage 49 guided in its reciprocations by lateral cars.

50' sliding in slots 51 in a pair ofupstanding brackets or supports 52, 52. This sliding carriage and the elements which it carries efi'ects'the feeding and severing of the labels from aroll'or spool 53 of the continuous strip '23 of the same, the roll or spool being supported iii-notched uprights 54, 54 rising from the base. From the spool the paper strip passes between two conveniently- "supported rollers 55, 56 with slightly roughened surfaces and then over a roller 7 57 52, 52. ,The'forwardly extended part of this 7 stationary guide member is accommodated in and supported bythe bottom wall or floor of an undercut groove 64 in the top of the sliding carriage 49, the undercut feature being provided by two lengthwiseflplates or bars '65, 65 fastened to the topof the carria-ge and overlyingv the main body of the groove cut lengthwise in thetop; face. To facilitate the entrance of the paper strip to such guide when a new strip is being inserted its mouthtowardthe spool is flared or enlarged. As is shown in the various figures of the drawings thisguide-member is of;practi'cally the same width as the paper strip and effectively guides it forwardly in its intermittent or interrupted travel, the memben having its bottom wall between its two oppositelydisposed bent or grooved portions which receive and guidethe edges of the aper cut away .at 66 to expose the top surfece of the'slide or carriage beneath. 1 In'order to clamp or grip the paper to the it and to release such paper tape during theback movement of the slide, the followinginstrumentalities have been provided. On a cross-piece 67 mountedon the carriage above the side-bars 65, 65 the forward end of a leaf spring 68 is fastened by means "of screws 69, 69, the rear end of the spring, by screws 70, 70, beingsecured to ;a shoe 71 adapted tobearfon the top face of the paper ribbon to press it down and thus clamp on grip it to the slide so that as thelattermoves' toward the molding machine it will advance the paper with it. To raise such shoe 'away ffro'm the paper during its retrograde movement and thus not inter-' transverse shaft 7 5 having a bearing in the 'loweizpart ofalbracket 7 6 mounted on top slide during its forward-travel to advance of one of the side-plates 65 near its end adjacent to the paper spool or roll. Shaft 7 5 has an upright rock-arm 77 pinned thereto by means of which the cam-shaft is oscillated, spaced stop-pins 78' and 79 fixed-to and projecting from the bracket 6 limiting its movements in opposite directions, During the reciprocations of the slide, bracket,

, arm, etc., the arm is rocked in opposite di-.

Referring now to the severing or cuttingoff mechanism of this appliance, it will be observed that a spring-plate 90 has two spaced legs 91 and 92 with spring action tending torise fastened byscrews 93, 93 on top of the sliding carriage side-bars 65, 65, one of the legs 92 being positioned between itscorresponding side-bar and bracket/76;

The other side of plate 90 is bentdown to provide a knife-blade or cutter 94 with its lower horizontal edge sharpened. On top the plate 90 has a transverse cam-bar 95 fixed thereto in any approved manner. Atthe front end of the apparatus on a cro'ss-.

shaft or rod 100 a cam-member 101 is rockingly hung by means of two parallel, upwardly-extended arms 102 apertured in register or alinement for the reception of the shaft. To the top of one of these arms one end of a 'coil contractile spring 103 is secured, the other end being fastened to the corresponding side-frame 52. Rocking of the cam 101 in the direction of feed of the paper, that is, toward the molding machine, is limited by an abutment or stop: rod 104 mounted in the side-frames and against which the arms 102 are adapted to bear by reason of the contracting action of spring;

Ordinarily,the edge of they knife-blade 94. is above the paper label ribbon inthe stationary guide-member 62, but when the sliding carriage on which the knife is mountedreaches theend .of its forward stroke, cam

' 95 comes under cam 101 thus forcing the knife-blade down close to the end of the carriage thus severing the projectingv label, the end: of the carriage :acting as one of the shear elements with which the knife-blade cooperates. During the retraction of the carriage, cam 101 rocks somewhat moving arms 102 away from the stop-rod 104, thus permitting cam 95, to passzeasily under it without depressing the cutting blade.

To support the label .-1n proper position preliminary ;to its application to the batch of dough,l' I employ a slotted plate 110 through the :slot 111. of which the label is, adapted to. pass, the plate being secured to the front ends of tworo'ds- 112 and 113- slidable in bearings in a cross-bar 114 transversely connectingftogether the side-frames,

and in bearings inears 115,;on a plate 116 fastened to the underside of the carriage.

Each of these slots is surrounded by a coiled spring 117 adapted to. bear at one end against acollar 118 on and pirmed to the rod. and at its other end against. a collar 119 slidable on the rod. Thus, the element 110 has a limited play relative to the other companion parts ofthe mechanism.

Referring now tothe detailed mechanism ofthe tripping or controlling appliance it will be perceived that the trip-plateor trigf ger 22 is fastened to a; shaft or rod 120 oscillatory in main bearings 200, 200 10- J cated at opposite ends and also in spaced bearings 121,122of a support1123 hinged to a bracket 124 at 125 for adjustment ofthe cooperating'parts as will be readily understood from the further description. Between these hearings 121, 122 the shaft has a collar 126 fixed thereto and carrying an outstanding arm: 127 .provided a at its end with a handle or;knob 128. Loose'onthe shaft so as to be capable of rocking thereon is a lever 129 vequipped witha cam 130 and a beveled, notched catch 131 pivoted at 132,

equipped with a handleor finger-piece 133 and a spring 134 tending to rock the catch into operative position, the arm 127 ordinarily residing in the notch of the catcharm, thus completing an operative rigid connection between the shaft and the cam,

whereby the rocking of the former oscillates the latter.

Bracket 124 has threealined bearings140,

141, and 142 for an oscillatory shaft or rod v 143 carrying at its upper portion a cam 144 in cooperative relation with cam andsecured to itssupporting'shaft by an arm 145. This cam 144. is rocked inwardly toward its companion operating cam 130 by a torsional spring 146 surrounding the shaft and having its ends secured respectively to the bracket and to anarm 147 fixed to'the shaft.

At 150 shaft 143 has a disengageable con nection with the upper round portion of the square shaft 40 and in order to swing'flor re store the shutter or trip 22 intothe path of travel of the batches of dough, after one'of them has passed and operatedit, a contrace tile spring. is connected to an end of lever129 and at its other end to the shank of the handle of the joint 150. 1

Assuming that the drumor cylinder of the molding machine and the grooved pulley 31- of the labeling appliance are constantly rotating, and that the latter is rcstrained from operating bylever 35 engaging pin orlug 30, and that the other elements are in the positions shown in the drawings, the operation of the apparatus occurs.practically as'follov s When a batch of-dough in its 'progress'or travel through v the molding machine arrives at the hinged trip-plate or trig'g'er 221it willpush it back in passing by, thus rocking the shaft 120 and by coacting cams 130, 144 turning the combination shaft 14:3, l0,-thus carrying cam .42 inwardly and by coactio'n with arm 43 rocking lever releasing lug 30, thereby permitting pulley to turn shaft 28 one complete revolution before which time the 'trip plate or trigger 22 will have returned to its original position under the actionof sprlnglGO and lever '35 will havecome back a into "the'circular path of travel of lug or pin 30, thus insuring that but one Complete revolution will be brought about. Such single revolution of shaft 28 through the connecting rod l6 effects a complete reciprocation of the sliding carriage, it being observed that when lever stopsthe turning of shaft 28 the connecting rod will be in its reai'mo-st position of travel with the wristpin d5 on dead center. I

During the advance stroke ofthe carriage, arm 77 is in its forward position as shown in 'Figs. 2' and '3, thus permitting-shoe 7-1 to of its forward movement arm 77 strikes abutment Slandis shifted or rocked to the left'thus lifting shoe 71 through the action of cam 7 4 which consequently does not grip the paper during the backward stroke. At the end of such retrograde movement, however, arm 77 strikes stop screw 80 and is rocked to depress the shoe on the paper ready for the next advance movement.

To those skilled in this art it will be apparent that the intention is not limited and i restricted to the precise and exact details 55 of structure presented but rat-her thatthe invention is capable of a. variety of embodiments and consequently many minor, me chanical changes may be incorporated in the apparatus illustrated and described Without departure from the heart and essence of the invention and without the sacrifice of any of its substantial I claim: a V '1.
